<-- back to Brakes
Rear brakes are traditional twin-shoe type, with manual adjusters of the wedge-and-tappet kind.

Overview
The same rear brake drum was used 1967-1994. It is an 8" diameter cast iron drum, that fits 1-3/8 wide brake shoes.
Starting from Oct 1989, Sunny Trucks started using a different brake shoe — while still using the same drum as early 1200s. These late model 1200s use a self-adjusting rear brake system. Aside from the drum, all the parts differ from earlier rear brakes.

Finned Alloy Brake Drums
Works Racing
Finned drums like these were offered by Datsun Competition in Japan.

Datsun Competition Dept supplied it's favoured teams with many experimental parts that were never sold over the counter. 1200s had alloy drums and calipers fitted as wellas the alloy diff heads from the wagons.
Isuzu Bellett
1969-1971 Isuzu Bellet 1600 GT (model G161) featured ALFIN rear brake drums.
* 3 outer holes on face * keyhole-shaped slot for adjusting brakes on face * 8" diameter * marked "Izumi Al-Fin" * about POST 2.22 kg each
Datsun Z-car
Larger 9" alloy drum are used on all S30 models (1971-1978 Fairlady/240Z/260Z/280Z). All 1200 brakes are 8", so the backing plate with brake shoes needs to be switched.

Datsun Roadster
1968-1970 Datsun roadster 1600/2000 used a finned alloy brake drum similar to the 240Z unit. 1965-1967 used cast iron version.
Nissan 43206-25500 * 9" diameter * lug holes for 7/16" studs (240Z uses metric studs) * center hole 70mm? (240Z is 68mm) * no brake adjuster hole (which 240Z requires) * squared-off fins (240Z fins are tapering) * height is about .090" different vs 240Z drums
Roadster axles do not have a centering flange, so the size of the lug holes is critical for correct drum centering. The 240Z drums have slightly larger holes and so will not center positively on roadster axles. An adapter can be fabricated for use in fitting 240Z drums on a roadster, which will also correct the drum height. It is close enough that some have used no adapter with varying success.
Roadster drums lack the adjuster hole which 240Z drums have
Weight
